MailPace

MailPace is a fast & Reliable Transactional Email.

Overview

MailPace is a SMTP provider which can be used on Clever Cloud to send emails.

MailPace provides an HTTPS API, SMTP Server and several libraries for sending emails that completely removes the need for any email setup or active email management. Emails sent through the MailPace API can come from any address for any domain that you are able to verify ownership of through a simple DNS update.

Add-on configuration

Create the add-on from Clever Cloud’s Console. You need to verify you domain name by adding the provided DNS entry in your DNS provider’s dashboard. Then, you will get an API KEY that you should add to your application (as environment variable with PHP, see section below).

• Host : smtp.mailpace.com
• Port : 25, 465, 587, 2525
• User : API KEY
• Password : API KEY
• Encryption : usage of TLS or STARTTLS are highly recommended.

PHP mail() function usage

You have to turn TLS on with port 465 (environment variable CC_MTA_SERVER_USE_TLS=true) to make Mailpace working. Enable STARTTLS allows to use another port.

These environment variables have to be set with the value of :

• CC_MTA_SERVER_HOST: Host of MailPace’s SMTP server is smtp.mailpace.com.
• CC_MTA_SERVER_PORT: Server port has to be set to 465. Defaults to 465 whether TLS is enabled or not.
• CC_MTA_AUTH_USER: User to authenticate to MailPace’s SMTP server has to be set with MAILPACE_API_KEY.
• CC_MTA_AUTH_PASSWORD: Password to authenticate to the SMTP server has to be set with MAILPACE_API_KEY.
• CC_MTA_SERVER_USE_TLS: Have to be enabled. Defaults to true.
• CC_MTA_SERVER_STARTTLS: Enable or disable STARTTLS. Defaults to false.
• CC_MTA_SERVER_AUTH_METHOD: Authentication has to be enabled. Defaults to on.

Then, redeploy your application on Clever Cloud for the changes to take effect. A few minutes later, your application will be able to send mails with mail() function thanks to MailPace’s SMTP server.
